Example text
O Interface circuits for external input and output (I/O). These circuits (commonly called ‘ports’) simplify the connection of peripheral devices such as printers, modems, mice, and joysticks. g. an Intel 8086, 8088, 80286, 80386, 80486, or Pentium). The microprocessor is crucial to the overall performance of the system. Indeed, successivegenerations of PC are normally categorized by reference to the type of chip used. The ‘original’ PC used an 8088, AT systems are based on an 80286, ’386 machines use an 80386, and so on.
Some boards will not work if they are present in the same machine as other devices. An example of this occurred in the PC of one of the authors. It was fitted with a PCI SCSI card that allowed a SCSI scanner to work very well. All was well until the scanner and its SCSI cable were removed. After this, the IDE CD-ROM drive eject button caused the system to reboot. Removing the now unused PCI SCSI card failed to resolve the problem. It had to be reinserted, the driver removed via the Windows 98 Control Panel and the card removed again before a reboot caused the ‘new hardware found’ dialogue.
2 PC chipset Historical note: With PC specificationsthings may not always be what they seem. The original Pentium processor with its 64-bit data bus promised to offer PC users the advantages of 64-bit processing. In fact, Pentium architecture is based on two interconnected 32-bit '486-type processors. As far as memory is concerned and because of its 32bit address bus, the Pentium is able to address exactly the same range as its predecessor. Not surprisingly, many people who rushed out to purchase the first Pentium-based systems were very disappointed with their performance -there must be a moral here somewhere!
